Fig 10 The objective color elements as viewed and estimated; general congruency is observed among the cervical (C), middle (M) and incisal (I) thirds amongst the maxillary triad. A multitude of hues is found at the incisal third due to the phenomena of opalescence and counter-opalescence. Chroma is more pro- nounced at the cervical third due to the thickness of dentin. 31 In all instances Value is highest at the middle third, due to the fact that the enamel and dentin present an equilibrium in terms of thickness ratios. 32
